Metallica have unveiled a new song titled “The Lords Of Summer” during the first show of their Metallica By Request tour.

The early fan response to the new song seems positive, with some aggressive thrash riffage, double-kick and harmonized soloing. It seems to fit somewhere alongside the more …And Justice For All-like moments of Death Magnetic.

Metallica By Request allows fans to vote on the set list. Upon purchasing tickets online, fans receive an email with a code allowing them to cast their ballots. Voting for the South American leg of the tour has been completed, but European fans can vote until May 16, and those heading to the Heavy Montreal festival can vote until August 1. The band also allowed Bogota audience members to pick one song towards the end of the set, choosing between “Whiskey In The Jar,” “Ride The Lightning” and “Hero Of The Day.”
